ADXL359 data sheet

GENERAL DESCRIPTION

The EVAL-ADXL359Z is a simple evaluation board that allows quick evaluation of the performance of the ADXL359, low noise, low power accelerometer. The EVAL- ADXL359Z is ideal for evaluation of the ADXL359 in an existing system because the stiffness and the small size of the EVAL-ADXL359Z minimizes the effect of the board on both the system and acceleration measurements.
The ADXL359 is a low noise density, low 0 g offset drift, low power, 3-axis microelectromechanical system (MEMS) accelerometer with selectable measurement range (±10 g, ±20 g, and ±40 g). The ADXL359 offers industrial leading noise, minimal offset drift over temperature, and long-term stability, enabling precision applications with minimal calibration.
The low drift, low noise, and low power ADXL359 enables accurate tilt measurement in an environment with high vibration, such as airborne inertial measurement units (IMUs). The low noise over higher frequencies is ideal for wireless condition monitoring.
The ADXL359 multifunction pin names may be referenced only by their relevant function for either the serial peripheral interface (SPI) or limited I2C interface.
For full details on the ADXL359, see the ADXL359 data sheet, which should be consulted in conjunction with this user guide when using the EVAL-ADXL359Z evaluation board.

EVALUATION BOARD HARDWARE

The EVAL-ADXL359Z allows users to access the individual connections of the ADXL359 and includes decoupling capacitors for the supplies, a few discrete resistors that provide isolation on the V1P8ANA and V1P8DIG pins, and two 6-pin headers. Refer to the ADXL359 data sheet for more details on the specific pin definitions. The power supplies for the ADXL359 are decoupled using multiple 0.1 F ceramic (0603) capacitors.
The EVAL-ADXL359Z uses two 6-pin headers and two 3-pin headers to provide access to all pins. The P1 header provides access to VDDIO, VDD (which connects to the ADXL359 VSUPPLY pin), VSS/VSSIO (supply common connection), INT1, INT2, and DRDY, as shown in Figure 3.

Figure 3. P1 Header Connections

The P2 header provides access to V1P8ANA, SCLK/VSSIO, V1P8DIG, MOIS/SDA, and MISO/ASEL, as shown in Figure 4.

Figure 4. P2 Header Connections

The P3 header provides access to CS_N/SCL, as shown in Figure 5.

Figure 5. Header P3 CS_N/SCL Access

The P4 header provides another connection to VDDIO and ground. The vias or headers allow the EVAL-ADXL359Z to attach to either a prototyping breadboard or a printed circuit board (PCB) in an existing user system. Four holes are provided in the corners of the EVAL-ADXL359Z for mechanical attachment of the EVALADXL359Z in many applications. An external host processor is required for communication to the ADXL359.
The dimensions of the EVAL-ADXL359Z are 0.8 in × 0.8 in.

EVALUATION BOARD CIRCUITRY

The ADXL359 has two power modes. The device can be powered either by integrated, low dropout (LDO) regulators or by external user supplied 1.8 V regulated supplies. Refer to the ADXL359 data sheet for more information.

HANDLING CONSIDERATIONS

The EVAL-ADXL359Z is not reverse polarity protected. Reversing of any of the supply connections, including the VSS and VSSIO pins, can cause damage to the ADXL359.
Dropping the EVAL-ADXL359Z on a hard surface can generate several thousand g of acceleration, which can exceed the ADXL359 data sheet absolute maximum limits.
